I think Verilog-A has to start out replacing Spice for a few
communities where its flexibility is crucial; once it gains
acceptance there, it will snowball. But its acceptance in
the compact modeling community does not depend strongly on
integration; the communities where integration is important
don't need its flexibility and are adequately served by
Spice, so what's the benefit for them? (Power MOS models
still use MOS level 3!)

That was board level stuff so I could bread-board it easily and didn't have to simulate it. These days most of the bits are integrated into single chips and can't be bread-boarded so simulation is the only way to design and verify. It is crucial that [System]Verilog-AMS is a single language that can describe high level logic down to single transistors (and works equally well for all the designers) if mixed signal SoC is to be commercially viable for more than a few (wealthy) design houses.
